Castiel’s body, possessed by the Leviathans and leaking black ooze, walks over to Dean, who calls to the unconscious Bobby. As Bobby wakes up, Dean distracts the Leviathans and says that the host body will soon explode. The Leviathans say that they’ll be back for Dean and stagger out of Crowley’s lab, unaware that down the hallway, Sam is struggling with Lucifer. Lucifer tells Sam that the two of them are real, but everything else is a hallucination and Sam is still in the cage in Hell.
Dean and Bobby arrive and Sam snaps out of his hallucination for the moment. They go after the Leviathans. Meanwhile, the Leviathans move Castiel’s vessel into a nearby municipal water supply. As the brothers and Bobby arrive, they watch Castiel’s body sink beneath the surface. A black vortex of liquid spreads out and the trio realizes that the water feeds into the public supply. Dean finds Castiel’s discarded trenchcoat and they figure that then angel is gone for good.
Across the area, people use the water. A young girl, Annie, drinks from a water fountain, shakes, and then smiles. A mechanic, Edgar, notices his sink vibrating. When he examines it, black fluid explodes out of the faucet and sprays in his face.
Sam is trying to sleep and hears Lucifer’s voice in his head. Dean wakes him up and offers him some water, and Sam takes it with his injured hand. While Dean checks on it, Lucifer sits nearby and mocks Dean’s efforts. Bobby hasn’t got any leads but figures the Leviathans will go public soon enough. Dean insists on talking about Sam’s situation, and Sam explains that he’s having trouble figuring out what’s real. He insists that he didn’t talk about it with them because they had enough going on, but admits that it’s getting more specific and he’s seeing Lucifer. When Dean points out that it doesn’t make sense for Lucifer to create a life for Sam, Sam and the hallucinatory Lucifer explain that there has to be something to take away from Sam for it to be torture. It’s a post-apocalyptic mess because it wouldn’t seem like Sam’s life if it wasn’t a mess. Dean realizes that Sam is seeing Lucifer and reminds him that it’s not real, but Sam points out that Lucifer is saying the same thing about Dean.

Once they leave, Jody tries to get out of bed and find her purse.

He tells Sam that it only ends when Sam can’t take it anymore and looks at the knife. Sam yells at him to shut up and Bobby comes in to find him yelling at empty air. He offers Sam a beer and says that Sam has beaten the Devil before. Sam sees Lucifer ram a poker through Bobby’s back and out his chest. The local phone rings and Bobby picks up.

Sam draws his gun and shoots, but his bullets have no effect. Lucifer suggests that he shoot himself.
